I can create a symlink to a file, but when I attempt to create a hard link, I get `Function not implemented`. What do I need to install to be able to create a hard link?

root@NAS:/mnt/user/Data/linktest# ls -la

drwxrwxrwx 1 root   root   0 Sep  7 11:00 ./
drwxrwxrwx 1 nobody users 32 Sep  7 11:00 ../

What is your Settings -> Global Share Settings -> Tunable (support hard links) set to?

It was set to "No". After stopping the array, changing it to "Yes" and starting the array, creating a hard link works like a charm.

 

Thanks! I would have never thought to look there.
